VLAN enabled ports are generally categorized in one of two ways, tagged or untagged. These may also be referred to as “trunk” or “access” respectively. The purpose of a tagged or “trunked” port is to pass traffic for multiple VLAN’s, whereas an untagged or “access” port accepts traffic for only a single VLAN. Generally speaking, trunk ports will link switches, and access ports will link to end devices.

然后第三行是规律的：We have been working 22/7 on the video for the first episode of the PhpStorm EAP. If we gave you a clue, it would be easy as pi.

仔细看一下就会发现是倒序
比较明显是倒序的，先尝试复原：
fun main() {
val string = ".spleh A+lrtC/dmC .thgis fo tuo si ti semitemos ,etihw si txet nehw sa drah kooL .tseretni wohs dluohs uoy ecalp a si ,dessecorp si xat hctuD erehw esac ehT .sedih tseuq fo txen eht erehw si ,deificeps era segaugnal cificeps-niamod tcudorp ehT"
print(string.reversed())
}
会得到：The product domain-specific languages are specified, is where the next of quest hides. The case where Dutch tax is processed, is a place you should show interest. Look hard as when text is white, sometimes it is out of sight. Cmd/Ctrl+A helps.
复制出来可以得到：This is our 20th year as a company, we have shared numbers in our JetBrains Annual report, sharing the section with 18,650 numbers will progress your quest.
能勉强看出来是：Did you know JetBrains is always hiring? Check out the kareers(careers) page and see if there is a job for you or a quest challenge to go further at least.
JetBrains has a lot of products, but there is one that looks like a joke on our Products page, you should start there… (hint: use Chrome Incognito mode)
产品页中有一个看起来像是个玩笑？提示用Chrome的无痕浏览。
其实还有一个更重要的重点：
